Rick N. MI Posted February 3 Share Posted February 3 Adjust the ground balance on the board in disc and you will gain quite a bit more depth. You can a little negative that is Monte's power balancing I sure you know. I adjusted my gb in all metal and it's to hot in disc. It's one my favorites. Keith Southern has a youtube video showing one he adjusted. 2 Link to comment https://www.detectorprospector.com/topic/27653-just-picked-up-a-very-nice-tesoro-lobo/#findComment-290247 Share on other sites More sharing options...

We only ever see Supertraq in England. Never seen the original, a special tool.

Rick N. MI Posted February 3 Share Posted February 3 The original Lobo would be interesting. It has an external ground balance. I wouldn't mind finding one of those. 2 Link to comment https://www.detectorprospector.com/topic/27653-just-picked-up-a-very-nice-tesoro-lobo/#findComment-290259 Share on other sites More sharing options...

Never seen the original, a special tool. Jealous! Their original 20 kHz Lobo (and original Diablo) was designed by Tesoro founder Jack Gifford. Dave Johnson designed the 17.5 kHz Lobo SuperTRAQ and Diablo II, totally different detectors, different coils. The newer 17.5 kHz coil have the female connector shown below. The older coils look the same but have male pins on the connector instead to keep the two from getting mixed up. The original Lobo had a manual adjustable ground balance in all metal mode. The SuperTRAQ runs in ground tracking in all metal mode. Both when switched to disc mode lock in the last ground balance setting taken from the all metal mode. So you always wanted to ground balance first in all metal before switching to disc mode. 3 1 Link to comment https://www.detectorprospector.com/topic/27653-just-picked-up-a-very-nice-tesoro-lobo/#findComment-290682 Share on other sites More sharing options...

This made the machine less effective at nugget hunting while in disc mode. The SuperTRAQ solved this by running in ground tracking in all metal mode, then when you switched to disc mode it locked in the last ground balance setting taken from the all metal mode. So with the ST you always wanted to ground balance first in all metal before switching to disc mode. After seeing this thread, I dug out my old original Lobo. According to the manual packed away with the machine (probably first time I ever read it! 🫢), the GB affects discriminate mode also. Perhaps Disc GB is offset positive relative to the AM ground balance by means of that trim pot...don't know about that. Anybody ever use a concentric on the original Lobo? They made an elliptical concentric for it. I think I recall reading in some factory literature that the concentric would be more sensitive to very small items at the expense of performance on real hot soil. I only have the 10x5 wIdescan and never saw a concentric.

Thanks for the update, I’ve corrected my post. 2 Link to comment https://www.detectorprospector.com/topic/27653-just-picked-up-a-very-nice-tesoro-lobo/#findComment-293475 Share on other sites More sharing options...
J-ROB Posted March 16 Share Posted March 16 Were it not for this thread, I never would have researched it. I'm sure you're 100% on everything else though! 🫠 Over here in the Mid Atlantic region, I probably won't be doing too much nugget shootin', so I'm certainly glad to have adjustable GB in Disc Mode.
